CloudDBError: java.net.UnknownHostException: Host is unresolved: clouddb.appinventor.mit.edu

Thank you @SteveJG for responding quickly, Based on your idea, I used an alternate solution to solve the problem. This is what I did-

  1. I added another screen where there is no CloudDB to avoid toast errors.
  2. Then I added the Net Extension (Thank you @vknow360 for the extension) to check the network connectivity.
  3. I added the OnDissconnect block and redirected to the new screen with start value as the current screen name.
  4. And in the new screen I added the OnConnect block and used the open another screen with the screenName as the start value.

When the network is gone it will automatically go to the new screen. When network is back, it will come to the original screen automatically. So, the problem is solved

Thank you :slightly_smiling_face:
